DS90UB935-Q1: GPIO and POC questions

Part Number: DS90UB935-Q1


Dear team,

Could you please help answer below questions?

1. When powering on, before PDB pull high, GPIO is in Hi-Z mode, right?

2. When the POC is turned off quickly, and then is turned on quickly, there will be a pulse(3.54V, 300mA) coupled to the serializer. Is there any protection mechanism inside our chip to against this pulse?

Thanks & Best Regards,

Sherry
